A helicopter attempted to take off while a rope remained tied to the forward fuselage. The nose pitched down, the aircraft rolled inverted upon water impact, and the pilot sustained back injuries.

What happened

The helicopter was attempting to initiate a takeoff when it became evident that a rope was still attached to the forward fuselage tiedown point. As the aircraft began its rotation, a witness observed the nose pitching downward while the tail lifted toward a near-vertical attitude. Despite the pilot's attempt to inflate the floats after the aircraft entered the water, the helicopter rolled completely inverted following the impact. The pilot managed to escape the submerged aircraft and swam to a nearby raft. During the violent impact sequence, the pilot sustained back injuries.

Findings

The primary factor contributing to the accident was the failure to remove the tow rope prior to initiating takeoff. This oversight caused an immediate loss of pitch control and resulted in the inverted water landing.

Probable cause

The pilot's failure to remove a tow rope from the forward fuselage during takeoff, which resulted in loss of control and an inverted water impact.
